The box has a shape of cube. The volume of cube with side s in is
Since Harriet uses a box of volume 216 cubic inches, then
and, therefore,
Note that then
Answer: the length of each side of the box is 6 inches.
The measures of angle POS and angle POQ will be 30° and 60° respectively.
From the information given, Lara constructed angle POQ and then used a compass and straightedge to accurately construct line segment OS.
The value of POS will be 30°. Therefore the value of POQ will be twice of POS which will be:
= 2 × 30°
= 60°

Answer:
The answer is
m<POS= 30 degrees, m<POQ=60 degrees.
Step-by-step explanation:
B. (3x + 4)(x + 4)
C. (3x – 4)(x – 4)
D. (3x – 4)(x + 4)
Answer:
The factored form of the expression 3x + 8x – 16 is (3x -4) (x + 4) .
Option (D) is correct.
Step-by-step explanation:
As the expression given in the question be.
3x (x + 4) - 4 (x +4) = 0
(3x -4) (x + 4) = 0
Therefore the factored form of the expression 3x + 8x – 16 is (3x -4) (x + 4) .
Option (D) is correct.
Answer:
= 8/6435
Step-by-step explanation:
Number of black balls = 8
Number of Brown balls = 5
Total number of balls = 8+5 = 13
Pr (8 balls picked at random are black ) =
Number of black balls / Total number of balls.
1st Pr ( 8 balls picked are black) = 8/13
Pr (2nd random pick) = 7/12
Pr (3rd random pick) = 6/ 11
Pr (4th random pick) = 5/10
Pr (5th random pick) = 4/9
Pr (6th random pick) = 3/7
Pr (7th random pick) = 2/6
Pr (8th random pick) = 1/5
Pr (8 balls picked at random are black ) = 8/13 * 7/12 * 6/11 * 5/10 * 4/9 * 3/7 * 2/6 * 1/5
= 8/13 * 7/12 * 6/11 * 1/2 * 4/9 * 3/7 * 1/3 * 1/5
= 8/6435
But pls note, I solved it such that there wasn't a replacement after each pick.
